Description

Technical Field

[0001] The utility model relates to the technical field of boarding ladders, and more particularly to a wave-shaped boarding ladder. Background Art

[0002] Existing automatic boarding stairs only have an inclined section and upper and lower horizontal sections. For example, the Chinese patent publication number CN220948552 U, the publication date of May 14, 2024, is titled "An automatic escalator for transporting passengers on board an aircraft." This application discloses an automatic escalator for transporting passengers on board an aircraft, wherein the escalator body is rotatably connected to a transport vehicle via a rotating structure. The escalator body can rotate around the rotating structure under the drive of a first hydraulic cylinder, so that the height of the escalator can be adjusted according to the cabin door height of different aircraft models, thereby improving the convenience of passengers boarding the aircraft. However, for some special circumstances, passengers need to stop or slow down and wave their hands during the escalator ride. The application does not contain corresponding technical means, and when the cabin door height is high, passengers may feel fear when rising to the upper part of the inclined section. Therefore, the existing technology still needs to be further improved. Utility Model Content

[0003] The utility model overcomes the shortcomings of the prior art that the passengers cannot stop or slow down to wave their hands during the boarding process and that the passengers may feel fear when they rise to the upper part of the inclined section. The utility model provides a wave-shaped boarding ladder that enables passengers to make a short stop during the boarding process and can freely control the length of the stop.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a wave-shaped boarding ladder, comprising a transport vehicle and a boarding ladder installed on the transport vehicle, the boarding ladder comprising a ladder path system, the ladder path system comprising an inclined section, the two ends of the inclined section being respectively connected to an upper horizontal section and a lower horizontal section, and at least one platform is provided on the inclined section.

[0005] The utility model includes a transport vehicle and a boarding ladder, wherein the boarding ladder adopts a non-linear design, and at least one platform is provided on the inclined section. When the passenger reaches the platform, the ladder system can stop, allowing the passenger to stay briefly on the platform. At the same time, the provision of the platform can also buffer the process of inclined upward movement, thereby alleviating the fear of the passengers during the elevator ride and making the entire elevator ride smoother.

[0006] Preferably, sensors for sensing passengers approaching the platform are respectively provided on the upper and lower inclined sections of the platform.

[0007] The upper and lower sensors can transmit the collected signals to the control system when they sense passengers passing by. The control system will adjust the speed of the boarding stair platform according to the different needs of the passengers.

[0008] Preferably, a starter assembly for controlling the start and stop of the platform is provided on one side of the platform. When a passenger stops on the platform, the starter assembly can be operated to resume the boarding ladder, so that the passenger can freely control the time of his / her stay.

[0009] Preferably, a truss is installed below the ladder system, and handrails are installed above both sides of the ladder system. The shapes of the handrails and the truss are adapted to the ladder system.

[0010] The truss installed under the ladder system increases the load-bearing capacity of the boarding ladder, and the handrail can ensure the safety of passengers during the operation of the boarding ladder. The shapes of both are adapted to the ladder system, making the overall structure of the boarding ladder more compact and the operation smoother.

[0011] Preferably, a drive system is provided on the truss, and the drive system includes a power assembly and a drive wheel.

[0012] The power assembly drives the drive wheels, which in turn drive the stairway system. The power assembly and drive wheels can be combined in various ways. The drive system also works with the control system to stop or change speed at the stairway platform.

[0013] Preferably, the power assembly is a hydraulic press, which is connected to the drive wheel via a coupling. The hydraulic press provides power, which drives the drive wheel via the coupling, and the drive wheel drives the ladder system to operate.

[0014] Preferably, the power assembly is a hydraulic press, and the hydraulic press is connected to the drive wheel via a chain. The hydraulic press and the drive wheel can also be connected via a chain.

[0015] Preferably, the power assembly adopts a driving main unit, and the driving main unit is connected to the driving wheel via a chain. The power assembly can also use the driving main unit to drive the driving wheel.

[0016] Preferably, the truss is further provided with a manual wheel disc. The brake disc is designed with a manual wheel disc, which can be manually disced in an emergency to avoid secondary injuries.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The design of the platform on the elevator system, as well as the design of the sensor and the coordination of the starting components, enable passengers to make a short stop during the elevator ride and enable passengers to freely control how long to stop before continuing to operate;

[0019] (2) Design a platform at the inclined section of the ladder system so that passengers can have a smooth buffer after ascending to a certain height, eliminating the fear caused by excessive height;

[0020] (3) The shapes of the ladder system, trusses and handrails correspond to each other, making the overall structure of the boarding ladder compact, improving the load-bearing capacity, and making the operation of the boarding ladder more stable;

[0021] (4) The brake disc is designed to manually rotate the wheel. In an emergency, manual rotation of the wheel can avoid secondary injuries. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Example 1: In existing automatic boarding elevators, generally only an inclined section is provided. However, in some special cases, such as when you need to wave or stop temporarily during the ride, it is very inconvenient to only have an inclined section.

[0031] Therefore, the utility model proposes a wave-shaped boarding ladder to solve this problem. Figure 1 As shown, the transport vehicle 2 and the airstair 1 mounted on the transport vehicle 2 include a ladder path system 11. The ladder path system 11 includes an inclined section, with the ends of the inclined section connected to an upper horizontal section and a lower horizontal section, respectively. The inclined section adopts a non-linear design and is provided with at least one platform 111. In this embodiment, only one platform 111 is provided, and the ladder path system 11 is generally wavy. The provision of the platform 111 can provide a buffer during the inclined upward movement, thereby alleviating passengers' fear during the ride and making the entire operation more stable.

[0032] In addition, an articulated mechanism and a retractable hydraulic cylinder are provided between the boarding ladder 1 and the transport vehicle 2, which can adjust the height of the boarding ladder 1 to adapt to the heights of different aircraft cabin doors, making it more convenient for passengers to board the aircraft.

[0033] The boarding ladder 1 also includes a truss 12 and a handrail 13. The truss 12 is installed below the ladder path system 11, and the handrail 13 is installed above both sides of the ladder path system 11. The shapes of the truss 12 and the handrail 13 are adapted to the ladder path system 11, so that the entire boarding ladder 1 has a wavy design, which enables the boarding ladder 1 to rise in a wavy shape rather than a straight line during the process of transporting passengers.

[0034] Sensor 1 121 and sensor 2 122 are respectively provided on the inclined sections of the upper and lower parts of the ladder system 11 at a certain distance from the platform 111 for sensing passengers approaching the platform. When a passenger passes sensor 1 121 during the upward process or passes sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will sense the passenger and transmit the collected signal to the control system. After the control system receives the signal from sensor 1 121 or sensor 2 122, the control system will control and adjust the platform 111 of the ladder system 11 according to different situations. If a passenger passes sensor 2 122 during the upward process or passes sensor 1 121 during the downward process, neither sensor 1 121 nor sensor 2 122 will transmit a signal to the control system.

[0035] A starting assembly 123 is provided on one side of the platform 111. More specifically, the starting assembly 123 is mounted and fixed on the truss 12 at a position corresponding to the platform 111. The starting assembly 123 is fixed upright and can be easily operated by passengers. When the stairway stops running and the passenger stops at the platform 111, the passenger can operate the starting assembly 123 to resume operation of the stairway system 11. In addition, the starting assembly 123 can be a hand-touch switch or sensor induction method. The passenger can operate it by pressing the switch or placing his hand in the sensing area at the platform 111. After that, the hand-touch switch or sensor will transmit the collected signal to the control system, and the control system will restart the stairway system 11 to resume operation.

[0036] In this embodiment, the control system is provided with a plurality of modes, for example, a continuous operation mode: in this mode, no matter whether a passenger passes through sensor 121 during the upward process and arrives at platform 111, or a passenger passes through sensor 2 122 during the downward process and arrives at platform 111, the control system will not change the state of the ladder system 11, that is, the platform 111 is in normal speed operation, and the elevator does not stop or change speed; a low-speed operation mode: in this mode, when a passenger passes through sensor 121 during the upward process or passes through sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will transmit the collected signal to the control system. After the control system receives the signal, the control system will decelerate the platform 111 of the ladder system 11, so that when the passenger reaches platform 111, the ladder at platform 111 is in a low-speed operation state, but the elevator will not stop; a slow stop mode: when a passenger passes through sensor 12 1 or when passing sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will transmit the collected signal to the control system. After the control system receives the signal, the control system will continuously decelerate the platform 111 of the ladder system 11, so that the ladder starts to decelerate continuously after the passenger passes sensor 1 121 or sensor 2 122 until the speed drops to 0 at a certain position on the platform 111. The ladder system 11 will stop running, and the passenger can stay at the platform 111. When the passenger needs to continue to go up or down, the ladder system 11 can be started by operating the starting component. Of course, the control system is not limited to these modes. For different needs, after the control system receives the signal from sensor 1 121 or sensor 2 122, the control system can perform different operations. For special circumstances, on-site staff can also manually operate the control system to ensure the smooth completion of the work.

[0037] A manual turning wheel 1244 is also provided on the truss 12. Manual turning of the wheel in an emergency can avoid secondary injuries. If the manual turning wheel 1244 is not installed, the elevator can also be stopped by reversing the drive wheel.

[0038] Example 2: Figure 2 and Figure 3 As shown, a drive system 124 is provided on the truss 12. The installation location of the drive system 124 is not limited to the location shown in the accompanying drawings. The drive system 124 includes a power assembly and a drive wheel 1243. In this embodiment, the power assembly is a hydraulic press 1241. The hydraulic press 1241 and the drive wheel 1243 are connected by a coupling 1242. The drive wheels 1243 are mounted on both ends of the main shaft of the ladder system 11, and the steps 112 of the ladder system 11 are mounted on the main shaft. When the boarding ladder 1 is in normal operation, the hydraulic press 1241 provides power, which drives the drive wheels 1243 to rotate through the coupling 1242. The rotation of the drive wheels 1243 drives the main shaft, which in turn drives the steps 112 to rotate, thereby realizing the operation of the ladder system 11. When a passenger passes by sensor 1 121 during the upward process or by sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will transmit the collected signal to the control system. After receiving the signal, the control system will send a signal to the drive system 124 according to different modes. For example, in the low-speed operation mode, after receiving sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 124 to reduce the output power of the hydraulic press 1241, thereby reducing the rotation speed of the drive wheel 1243 through the coupling 1242, and then reducing the rotation speed of the main shaft driving the step 112, so that the platform 111 is in a low-speed operation state; in the slow stop mode, after receiving sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 124 to reduce the output power of the hydraulic press 1241, thereby reducing the rotation speed of the drive wheel 1243 through the coupling 1242, and then reducing the rotation speed of the step 112 driven by the main shaft, so that the platform 111 is in a low-speed operation state. 124 sends a signal to make the hydraulic press 1241 continuously reduce the output power, thereby continuously reducing the rotation speed of the driving wheel 1243 through the coupling 1242, and then continuously reducing the rotation speed of the main shaft driving the step 112. When the passenger reaches the platform 111, the hydraulic press 1241 will stop working, the driving wheel 1243 and the main shaft will stop rotating, and the ladder system 11 will stop running. After a certain period of time, the passenger can operate the starting component 123 to send a signal to the control system. After receiving the signal, the control system will send a signal to the drive system 124 to make the hydraulic press 1241 start working again, and the driving wheel 1243 will drive the main shaft to rotate again through the coupling 1242, and the main shaft will then drive the step 112 to rotate. The ladder system 11 starts running again, and the passengers can continue to go up or down to complete the elevator ride.

[0039] The coupling 1242 has high elasticity. When subjected to nominal torque, the rotation angle is 10 degrees, and when subjected to maximum torque, it is 25 degrees. It can reduce the natural vibration frequency of the shaft system. It also has good damping and vibration reduction characteristics. It can absorb part of the vibration energy, reduce the vibration amplitude when passing through the vibration point, and reduce the torsional vibration stress of the shaft section. When the power of the hydraulic press 1241 changes, it can be better transmitted to the drive wheel 1243.

[0040] Example 3: Figure 4 As shown, the coupling 1242 in the drive wheel can be replaced by a drive chain 1245, which connects the hydraulic press 1241 and the drive wheel 1243. When the boarding ladder 1 is in normal operation, the hydraulic press 1241 provides power, which drives the drive wheel 1243 to rotate through the drive chain 1245. The rotation of the drive wheel 1243 drives the main shaft, which in turn drives the steps 112 to rotate, realizing the operation of the ladder system 11. When a passenger passes by sensor 1 121 during the upward process or by sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will transmit the collected signal to the control system. After receiving the signal, the control system will send a signal to the drive system 124 according to different modes. For example, in the low-speed operation mode, after receiving the signal from sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 124 to reduce the output power of the hydraulic press 1241, thereby reducing the rotation speed of the drive wheel 1243 through the drive chain 1245, and then reducing the rotation speed of the main shaft driving the step 112, so that the platform 111 is in a low-speed operation state; in the slow stop mode, after receiving the signal from sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 124 to reduce the output power of the hydraulic press 1241, thereby reducing the rotation speed of the drive wheel 1243 through the drive chain 1245, and then reducing the rotation speed of the step 112 driven by the main shaft, so that the platform 111 is in a low-speed operation state. The hydraulic press 1241 sends a signal to continuously reduce the output power, thereby continuously reducing the rotation speed of the drive wheel 1243 through the drive chain 1245, and further continuously reducing the rotation speed of the main shaft driving the step 112. When the passenger reaches the platform 111, the hydraulic press 1241 stops working, the drive wheel 1243 and the main shaft both stop rotating, and the ladder system 11 stops operating. After a certain period of time, the passenger can operate the starting component 123 to send a signal to the control system. After receiving the signal, the control system sends a signal to the drive system 124 to restart the hydraulic press 1241. The drive wheel 1243 drives the main shaft to rotate again through the drive chain 1245, and the main shaft then drives the step 112 to rotate. The ladder system 11 resumes operation, and the passenger can continue to ascend or descend, completing the elevator journey. The hydraulic press 1241 can be installed on the outside of the truss 12 or on the inside of the truss 12. In this embodiment, the hydraulic press 1241 is installed on the outside of the truss 12.

[0041] Example 4: Figure 5 and Figure 6As shown, the power assembly in the drive system 124 can also be a drive main unit 1246, which is connected to the drive wheel 1243 via a drive chain 1245. When the boarding ladder 1 is in normal operation, the drive main unit 1246 provides power, which drives the drive wheel 1243 to rotate via the drive chain 1245. The rotation of the drive wheel 1243 drives the main shaft, which in turn drives the steps 112 to rotate, thereby realizing the operation of the ladder system 11. When a passenger passes by sensor 1 121 during the upward process or by sensor 2 122 during the downward process, sensor 1 121 or sensor 2 122 will transmit the collected signal to the control system. After receiving the signal, the control system will send a signal to the drive system 124 according to different modes. For example, in the low-speed operation mode, after receiving sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 124 to make the drive host 1246 reduce the output power, thereby reducing the rotation speed of the drive wheel 1243 through the drive chain 1245, and then reducing the rotation speed of the main shaft driving the ladder 112, so that the platform 111 is in a low-speed operation state; in the slow stop mode, after receiving sensor 1 121 or sensor 2 122, the control system will send a signal to the drive system 1 The control system 124 sends a signal to the drive unit 1246, causing it to continuously reduce its output power. This in turn reduces the rotation speed of the drive wheel 1243 via the drive chain 1245, and further reduces the rotation speed of the steps 112 driven by the main shaft. When the passenger reaches the platform 111, the drive unit 1246 stops working, and both the drive wheel 1243 and the main shaft stop rotating, causing the ladder system 11 to stop operating. After a certain period of time, the passenger can operate the starting component 123 to send a signal to the control system. Upon receiving the signal, the control system sends a signal to the drive system 124, causing the drive unit 1246 to restart. The drive wheel 1243 drives the main shaft again via the drive chain 1245, and the main shaft in turn drives the steps 112 to rotate. The ladder system 11 resumes operation, and the passenger can continue to ascend or descend, completing the elevator journey. The drive unit 1246 is mounted on the inner side of the truss 12.
